FOLDING BOX.

Application led June 21, 1926. Serial No. 117,336.

My invention relates to folding boxes and in particular to a box which,when unfolded, will assume an unfolded condition with the end walls andside walls of equal height.

e Heretofore, it has been regarded as im.-

possible and as being unknown in the trade to have a box which may bemoved from a partially folded condition in fiat sha e to a fully foldedand assembled condit1on, in 1o which the side walls of the box are ofthe same height as the end walls.

lt is my object to provide a box which may be ship ed in semi-foldedcondition in dat form and which can be easily assembled le into fullyassembled condition by simple movements of any unskilled person.

Feferring to the drawings:

Figure l is a plan view of the to of the box in semi-folded conditionready or shipment in its dat form;

Figure 2 is a similar view showing the side wall Haps in unfoldedposition for the purpose of illustration;

Figure 3 is a section on at Figure l;

Figure Il is a side elevation of the box just as it is being assembledinto its fully unfolded and assembled condition;

Figure 5 is a section on the line 5--5 of Figure l; Figure 6 is a sideelevation of the box in fully assembled and unfolded condition;

Fig. l is a view of the blank;

Fig. e is a perspective view of assembled expanded position.

Referring to the designates the bottom of the box which is provided withend walls 2 and 3 and side walls l and 5.. The end walls are turned overat their outer ends into flaps 6. The end the line 3-3 of the box inwalls are turned over at their sides so that there is an overlappingside liap 7, which lies beneath the end flap 6. Staples 8 are placedtherethrough. There are similar overlapping side flaps 7 which overlapeach otherat their inner corners 7a. .These side flaps are connectedintegrally with intermediate Haps 9 which are substantially triangularinshape. These intermediate .flaps are plonnected to theside iaps 7along a score inge a onal edges 11 which form the second side gle whilethe third or vertical o the trian side of the triangle is formed by .thescore l2 te along which line the intermediate iap is drawings in detail,.l

joined to the respective side walls 4 or 5. The side walls or 5 areformed with an inwardly folding side wall flap i3 which is folded alongthe scored line le which proceeds parallel to the top edge 15 of theside wall crossing the scores l2 and across the upper parts of theintermediate flaps, terminating at the edges 11 of the intermediatenaps. Thus, the side wall flap and the top of the intermediate flaps areada ted to fold inwardl This permits of the side walls being folde asusual, but, when in unfolded condition permits of their full vexpansionand the side walls being of the same height as the end walls and thebottom width. .When the box is expanded and opened up into its foldedform to make a box complete, it will be noted that the overlappingintermediate naps gradually assume a vertical position parallel to theinside of the endwalls 2 and 3, while the side walls assume a verticalposition and the daps are unfolded, as in Figure 5 and Figure 6.

lt will be understood that I desire to comprehend within my inventionsuch modifications as may be necessary to adapt it to varying conditionsand uses.

llavin thus fully described my invention, what l c aim as new and desireto secure by Letters Patent, is:

l. ln a collapsible box adapted to be erranged in semi-folded'at formand to be moved from that form into fully assembled form, thecombination of a bottom, end walls and side walls, said end walls andside walls when in fully assembled form being of the same height, equalto the width of the bottom, said side walls being folded upon themselveswhen the box is in collapsed condition.

Q. In combination in a box, of a bottom, end walls and side walls, saidside walls when in collapsed condition having upper portions folded uponeach other and so arranged that the box may be assembled in flat formand may be automatically unfolded from the assembled flat form to theassembled set-up condition with the side walls and end walls of the sameheight, equal d to the width of the bottom. l0., They are provided withfree di- 3. In combination in a box, a bottom, end walls and side walls,side aps attached to the end walls and intermediate a s connected to theside walls and to the si e flaps, said side walls being creased and theouter portions folded back onto the main portions thereof when the boxis arranged in semifolded fiat form.

4. In combination in a box of a bottom portion, end Wall portions, endliaps on the end wall portions, side Wall portions composed of main sidewall portions, intermediate liap portions and side flap portions, saidside `flap portions being adapted to fold over each otherbeneath the endaps of the end walls, means to fasten said end aps to the side aps andend walls, said parts being so arran ed that they may be folded in acollapse position flat and moved from the collapsed position to a fullexpanded osition with the intermediate aps paralle to the end Wallportions and at right angles to the main side wall portions, said sideWalls having portions ada tedto be folded when the box is in semi-foldedcollapsed position and extended in line with the main side Wall portionsWhen the box is in expanded position, the height of the end walls andside walls being equal to the width of the bottom.

5. In combination ina box adapted to be arranged in fiat form insemi-assembled condition and moved from thatcondition to fully assembledcondition automatically, a box blank having an integral bottom, hingedend walls, end aps hinged on the end Walls, hinged side walls consistingof main side wal ortions, intermediate flap portions and side apportions so arranged that when the box is 1n semi-folded flat conditionthe side flaps and side wall portions will be folded parallel to thebottom and end wall portions, the side flaps will be overlapping and theend aps overlapping the side flaps, While the intermediate flaps Willoverlap each other and the outer portions of the main side wall portionsoverlap each other, said main side wall portions having inwardly turnedflaps along the upper edges adapted to be inwardly folded when the boxis in flat condition and when said box is moved to an o en condition,the main side Wall flaps Wi l be extended to form parts of the sideWalls.

6. In a one piece box, la blank having a bottom portion, end wallportions hinged thereto, end lap portions hinged to the end Wallportions, side Hap portions hinged to the sides of the end Wall portionsand hinged on their inner edges diagonally to intermediate aps,intermediate iaps substantially triangular in shape having a free edge,main side Wall portions having sides thereof hinged to the adjacentintermediate flaps and the bottom thereof hinged to the bottom portionof the blank, said intermediate por'tlons and main side wall portionsbeing creased parallel to the hinged line of the main side Wall portionwith the bottom portion to form a flap which is folded back against theintermediate and main side wall portions when the'box is partiallyfolded for shipment and extended when the box is set up ready for use.

In testimony whereof I aiiix my signature.
